Halloween Horrors Scare Actors

I am one of the scare actors now. One of the 81 shortlisted actors for HH2011. But i am kinda scared. My role is not determined, i have no friends in halloween horrors, meaning i am alone in this and also, i am scared to role play in front of the those SP students. I am a very timid person, whatever but you have to understand how big this is going to be for me. I am not a very sociable person, i am in fact, an introvert.

So i am really scared to do this without a friend..
